Lateral Ankle Ligament Repair Is Not Only for Young Patients: Trends in Incidence and Demographics.

The purpose of this study was to examine the changes in annual incidence and patient population undergoing lateral ankle ligament repair (LALR) for the surgical treatment of chronic ankle instability. The IBM Watson Health MarketScan Database was queried for patients who underwent LALR from January 2009 to December 2019 based on CPT code 27698. Volume and incidence per 100 000 population were determined for annual sums, gender, age, and geographical regions based on population estimates from the United States Census Bureau. Future annual volumes were statistically projected with linear regression modeling to the year 2032. Overall, 160 457 LALR procedures were identified in the database from 2009 to 2019. Annual incidence increased 76.6% from 3.46 to 6.11 cases per 100 000 population, while estimates of annual volumes are projected to increase 61.5% from 19 829 to 32 033 procedures to the year 2032. Interestingly, the greatest increase in incidence was observed among patients above 70 years old, which might suggest older patients are staying active longer and desiring elective procedures to maintain their activity levels. As the incidence of LALR increases in older patients, more research will be needed to understand the unique surgical considerations and risk factors impacting patient-reported outcomes.Level of Evidence: Level IV.

Weightbearing Computed Tomography Can Accurately Detect Subtle Lisfranc Injury.

BACKGROUND: Early detection of Lisfranc injury is critical for improving clinical outcomes, but diagnosing subtle injury can be difficult. Weightbearing computed tomography (WBCT) allows evaluation of such injuries in 3 dimensions (3D) under physiologic load. This study aimed to assess the utility of 1-, 2-, and 3-dimensional measurements on WBCT to diagnose subtle injury in isolated ligamentous Lisfranc injuries. METHODS: Ten cadaveric specimens underwent WBCT evaluation of the Lisfranc joint complex in the intact state and subsequently with sequential sectioning of the dorsal Lisfranc ligament and interosseous Lisfranc ligament (IOL) to create subtle Lisfranc injury, and finally after transectioning of plantar Lisfranc ligament (PLL) to create the injury conditions for complete ligamentous Lisfranc injury. Measurements under static vertical tibial load of 80 kg were performed on WBCT images including (1) Lisfranc joint (medial cuneiform-base of second metatarsal) volume, (2) Lisfranc joint area, (3) C1-C2 intercuneiform area, (4) C1-M2 distance, (5) C1-C2 distance, (6) M1-M2 intermetatarsal distance, (7) first tarsometatarsal (TMT1) alignment, (8) second tarsometatarsal (TMT2) alignment, (9) TMT1 dorsal step-off distance, and (10) TMT2 dorsal step-off distance. RESULTS: In the subtle Lisfranc injury state, Lisfranc joint volume and area, C1-M2 distance, and M1-M2 distance measurements on WBCT significantly increased, when compared with the intact state (P values .001 to .014). Additionally, Lisfranc joint volume and area, C1-M2 distance, M1-M2 distance, TMT2 alignment, and TMT2 dorsal step-off measurements were increased in the complete Lisfranc injury state. Of all measurements, C1-M2 distance had the largest area under the curve (AUC) of 0.96 (sensitivity = 90%; specificity = 90%), followed by Lisfranc volume (AUC = 0.90; sensitivity = 80%; specificity = 80%) and Lisfranc area (AUC = 0.89; sensitivity = 80%; specificity = 100%). CONCLUSION: In a cadaveric model we found that WBCT scan can increase the diagnostic accuracy for subtle Lisfranc injury. Among the measurements, C1-M2 distance exhibited the highest level of accuracy. The 2D joint area and 3D joint volume also proved to be accurate, with 3D volume measurements of the Lisfranc joint displaying the most significant absolute difference between the intact state and increasing severity of Lisfranc injury. These findings suggest that 2D joint area and 3D joint volume may have potential as supplementary measurements to more accurately diagnose subtle Lisfranc injuries. CLINICAL RELEVANCE: WBCT may help surgeons detect subtle Lisfranc injuries.

3D kinematics of tibiotalar motion in patients with mobile bearing and fixed bearing total ankle arthroplasty: In vivo videofluoroscopic feasibility study.

BACKGROUND: As total ankle arthroplasty (TAA) is an increasingly common surgical intervention for patients with end-stage ankle arthritis, there is a need to better understand the dynamic performance of prosthetic implants during activities of daily living. Our purpose was to quantify and compare relative tibiotalar motion during gait in persons with a fixed-bearing (FB) and mobile-bearing (MB) total ankle arthroplasty. We hypothesized a FB prosthesis would have lower tibiotalar range of motion (ROM). METHODS: Patients at least 12 months postoperative with either a FB (n=5) or MB (n=3) total ankle arthroplasty were tested. We used high-speed biplanar videoradiography to quantify tibiotalar kinematics during self-selected gait. Angular and linear ROM in three axes were compared between the groups. RESULTS: ROM for dorsiflexion-plantarflexion, internal-external rotation, and inversion-eversion angles in FB subjects averaged 7.47±4.05°, 7.39±3.63°, and 4.51±2.13°, respectively. ROM in MB subjects averaged 6.74±2.04°, 6.28±4.51°, and 5.68±2.81°, respectively. Linear ROM along anteroposterior, mediolateral, and superior-inferior axes in FB subjects averaged 1.47±2.07 mm, 1.13±1.49 mm, and 0.28±0.30 mm, respectively. Linear ROM in MB subjects averaged 0.68±1.44 mm, 0.60±1.41 mm, and 0.20±0.13 mm, respectively. We found no significant difference between the two groups for any of these ROM parameters (p>0.05). CONCLUSION: Total ankle arthroplasty using either FB or MB design appears to confer similar ankle motion during the gait cycle in this biplanar fluoroscopic model.

Considering the cellular landscape in marrow stimulation techniques for cartilage repair.

BACKGROUND: Marrow stimulation is a common reparative approach to treat injuries to cartilage and other soft tissues (e.g., rotator cuff). It involves the recruitment of bone marrow elements and mesenchymal stem cells (MSCs) into the defect, theoretically initiating a regenerative process. However, the resulting repair tissue is often weak and susceptible to deterioration with time. The populations of cells at the marrow stimulation site (beyond MSCs), and their contribution to inflammation, vascularity, and fibrosis, may play a role in quality of the repair tissue. SUMMARY: In this review, we accomplish three goals: 1) systematically review clinical trials on the augmentation of marrow stimulation and evaluate their assumptions on the biological elements recruited; 2) detail the cellular populations in bone marrow and their impact on healing; and 3) highlight emerging technologies and approaches that could better guide these specific cell populations towards enhanced cartilage or soft tissue formation. KEY MESSAGES: We found that most clinical trials do not account for cell heterogeneity, nor do they specify the regenerative element recruited, and those that do typically utilize descriptions such as "clots", "elements", and "blood". Furthermore, our review of bone marrow cell populations demonstrates a dramatically heterogenous cell population, including hematopoietic cells, immune cells, fibroblasts, macrophages, and only a small population of MSCs. Finally, the field has developed numerous innovative techniques to enhance the chondrogenic potential (and reduce the anti-regenerative impacts) of these various cell types. We hope this review will guide approaches that account for cellular heterogeneity and improve marrow stimulation techniques to treat chondral defects.

Republication of "Assessment of Recovery From Geriatric Ankle Fracture Using the Life Space Mobility Assessment (LSA): A Pilot Study".

Background: The Life Space Assessment (LSA) is a validated outcomes measure that aims to assess the level of mobility and physical functioning within one's own environment following a medical event. We sought to study the recovery of geriatric ankle fracture patients utilizing the LSA. We hypothesized that the LSA would provide improved assessment of these patients and help identify key differences in operative and nonoperatively treated patients. Methods: Prospective observational study of geriatric patients age 65 years and older with an ankle fracture with 1-year follow-up. Operative versus nonoperative intervention was determined by the attending physician on a patient-specific basis. The LSA, Short Form-36 (SF-36), and visual analog pain scale (VAPS) were administered at predetermined intervals postinjury and scores were analyzed for significance. Results: 20 patients were enrolled in this study. 11 underwent surgery whereas 9 were treated nonoperatively. Regardless of treatment, the preinjury LSA score was 86.7. This significantly dropped to 20.6 at 6 weeks and recovered to 73.6 at 12 months. In the operative cohort, the LSA scores preinjury were 91.4 and improved to 87.6 after 1 year. The nonoperative group recorded 80.9 preinjury and only improved to 59.5 at 1 year (P = 0.007). There was no statistically significant difference when comparing the results of the SF-36 and VAPS to the LSA. Conclusion: The LSA was effective in assessing recovery in geriatric ankle fracture patients. A severe deficit in mobility was seen for the first 6 months of recovery regardless of treatment. Operative patients ultimately returned to their baseline LSA at 1 year while nonoperative patients did not. Outcomes from the VAS and SF-36 mirrored the LSA but were not found to be statistically significant. Level of Evidence: Level II.

Body Mass Index (BMI) Cutoffs and Racial, Ethnic, Sex, or Age Disparities in Patients Treated With Total Ankle Arthroplasty.

Background: The rising prevalence of obesity among American adults has disproportionately affected Black adults and women. Furthermore, body mass index (BMI) has historically been used as a relative contraindication to many total joint arthroplasty (TJA) procedures, including total ankle arthroplasty. The purpose of this study was to investigate potential disparities in patient eligibility for total ankle arthroplasty based on race, ethnicity, sex, and age by applying commonly used BMI cutoffs to the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Methods: Patients in the ACS-NSQIP database who underwent TAA from 2011 to 2020 were retrospectively reviewed in a cross-sectional analysis. BMI cutoffs of <50, <45, <40, and <35 were then applied. The eligibility rate for TAA was examined for each BMI cutoff, and findings were stratified by race, ethnicity, sex, and age. Independent t tests, chi-squared tests, and Fisher exact tests were performed to compare differences at an α = 0.05. Results: A total of 1215 of 1865 TAA patients (65.1%) were included after applying the exclusion criteria. Black patients had disproportionately lower rates of eligibility at the most stringent BMI cutoff of <35 (P = .004). Hispanic patients had generally lower rates of eligibility across all BMI cutoffs. In contrast, Asian American and Pacific Islander patients had higher rates of eligibility at the BMI cutoffs of <35 (P = .033) and <40 (P = .039), and White non-Hispanic patients had higher rates of eligibility across all BMI cutoffs. Females had lower eligibility rates across all BMI cutoffs. Ineligible patients were also younger compared to eligible patients across all BMI cutoffs. Conclusion: Stringent BMI cutoffs may disproportionately disqualify Black, female, and younger patients from receiving total ankle arthroplasty. Level of Evidence: Level III, retrospective cross-sectional study.

Elective Foot and Ankle Procedures in the Patients Greater than 65 Years of Age: Worth the Mobility Gains.

Chronic, non-traumatic pathologies of the foot and ankle can be mobility-limiting for patients of all ages. The objective of this study was to compare postoperative changes in LifeSpace Mobility Assessment (LSA) scores of adult and elderly patients following elective foot and ankle surgery. A prospective study of 184 patients undergoing elective ankle, hindfoot, and midfoot procedures conducted by one surgeon between 2015 and 2019 was undertaken. Patient-reported LSA scores were collected at preoperative, 6-month, and 12-month follow-up. Patient data was compared using an independent sample t-test for continuous, normally distributed data and a chi-squared or Fischer's exact test for categorical data. Alpha and beta were .05 and .8. Patients were divided based on age. 140 patients were observed in the younger (<65) group, 44 patients were observed in the elderly (≥65) group. The average LSA score of elderly patients at the preoperative visit was 58.3 (SD 38.0) vs 79.3 (SD 38.8) in the younger cohort (P = .041). Both patient cohorts saw decreased mobility at 3-month postoperative visits but surpassed preoperative mobility scores by 6 months and 1 year postop. No difference in average mobility score was observed between young (85.6, SD 36.1) and elderly (90.1, SD 34.3) cohorts at 1-year follow up. Given the increased rates of perioperative comorbidities and the heightened risks of intraoperative complications, physicians may be more inclined to manage elderly patients with longer periods of conservative treatment for similar pathologies. However, these results imply that elderly patients experience similar improvements after surgery to younger cohorts and should not be excluded from surgical consideration. Our results, in tandem with literature showing the deleterious effects of decreased mobility in the elderly, suggest that the discussion to pursue or hold surgical correction of chronic foot and ankle disease in patients over age 65 must consider the mobility benefits of surgery.

Association of First Metatarsal Phalangeal Joint Fusion for Hallux Rigidus With Patient-Reported Pain and Mental Health Outcomes in Patients Taking Psychotropic Medications.

Background: Limited literature examines the relationship between surgical outcomes in chronic foot and ankle conditions and concurrent psychiatric care. The present study aimed to investigate patient-reported and surgical outcomes of patients treated for a psychiatric disorder undergoing first metatarsophalangeal (MTP) fusion for hallux rigidus. We hypothesized that patients on psychotropic medications would have greater subjective pain preoperatively and less improvement in physical and mental functionality postoperatively when compared with nonmedicated patients. Methods: A single-center, retrospective review of prospectively collected data was conducted on 92 patients undergoing first MTP fusion with a preoperative diagnosis of hallux rigidus from 2015 to 2019. At their preoperative, 6-month postoperative, and 1-year postoperative visits, patients were administered visual analog pain scale (VAS) and 36-Item Short Form Health Survey (SF-36) functionality surveys. Patients were subsequently identified by chronic use of psychotropic medication preoperatively and grouped for analysis (MED, n = 42; NO MED, n = 50). Results: Postoperative mean VAS pain scores were lower for all studied patients at 6 months (VAS = 1.6 ± 2.3) and 1 year postoperatively (VAS = 1.1± 1.8) relative to the preoperative visit (VAS = 4.7 ± 2.8) (P ≤ .0001 and P ≤ .0001, respectively). No differences in mean VAS pain scores nor SF-36 physical component summary scores were detected at preoperative, 6-month, or 1-year visits between NO MED and MED groups. Mean SF-36 mental component summary scores for those in the MED group were lower at preoperative (NO MED = 83.8, MED = 71.8, P = .006) and 6-month postoperative (NO MED = 86.1, MED = 72.7, P = .037) visits than those in the NO MED group, a trend not observed at the 1-year postoperative mark (NO MED = 84.1, MED = 76.8, P = .228). There were no observed differences in operative time (P = .219), tourniquet time (P = .359), nor time to full weightbearing (P = .512) between MED and NO MED groups. Additionally, no differences in postoperative complication rates were observed between groups. Conclusion: In patients treated with psychotropically active medications with hallux rigidus, MTP Fusion appears to be a reasonable treatment choice with similar outcomes for patients requiring psychotropically active medications to the outcomes of those patients not requiring psychotropically active medications. Level of Evidence: Level III, retrospective comparative study.

Outcomes and Complications of Open Versus Minimally Invasive Repair of Acute Achilles Tendon Ruptures: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

BACKGROUND: An acute Achilles tendon rupture is one of the most common sports injuries, affecting 18 per 100,000 persons, and its operative repair has been evolving and increasing in frequency since the mid-1900s. Traditionally, open surgical repair has provided improved functional outcomes, reduced rerupture rates, and a quicker recovery and return to activities at the expense of increased wound complications such as infections and skin necrosis compared with nonoperative management. In 1977, Ma and Griffith introduced the percutaneous approach, and over the following decades, multiple improved techniques, and modifications thereof, have been described with comparable outcomes with open repair. PURPOSE: The current study aimed to provide updated level 1 evidence comparing open repair with minimally invasive surgery (MIS) through a comprehensive search of the literature published in English, Arabic, Spanish, Portuguese, and German while avoiding limitations of previous studies such as heterogeneous study designs and a small number of included trials. STUDY DESIGN: Meta-analysis; Level of evidence, 1. METHODS: Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, 2 independent team members searched several databases to identify randomized controlled trials (RCTs) comparing open repair and MIS of Achilles tendon ruptures. The primary outcomes were (1) functional outcomes, (2) reruptures, (3) sural nerve injuries, and (4) infections (deep/superficial), whereas the secondary outcomes were (1) skin complications, (2) adhesions, (3) other complications, (4) ankle range of motion, and (5) surgical time. RESULTS: There were 10 RCTs that qualified for the meta-analysis with a total of 522 patients. Overall, 260 (49.8%) patients underwent open repair, while 262 (50.2%) underwent MIS. The mean postoperative AOFAS score was 94.8 and 95.7 for open repair and MIS, respectively, with a nonsignificant difference (mean difference [MD], -0.73 [95% CI, -1.70 to 0.25]; P = .14; I2 = 0%). The pooled mean total complication rate was 15.5% (0%-36.4%) for open repair and 10.4% (0%-45.5%) for MIS, with a nonsignificant statistical difference (odds ratio [OR], 1.50 [95% CI, 0.87-2.57]; P = .14; I2 = 40%). The mean rerupture rate was 2.5% (0%-6.8%) for open repair versus 1.5% (0%-4.6%) for MIS, with a nonsignificant statistical difference (OR, 1.56 [95% CI, 0.42-5.70]; P = .50; I2 = 0%). No cases of sural nerve injuries were reported in the open repair group. The mean sural nerve injury rate was 3.4% (0%-7.3%) in the MIS group, which was statistically significant (OR, 0.16 [95% CI, 0.03-0.46]; P = .02; I2 = 0%). The mean overall superficial infection rate was 6.0% (0%-18.2%) and 0.4% (0%-4.5%) for open repair and MIS, respectively, with a statistically significant difference (OR, 5.70 [95% CI, 1.80-18.02]; P < .001; I2 = 0%). The mean overall deep infection rate reported in the open repair group was 1.4% (0%-5.0%), while no deep infection was reported in the MIS group, with no statistically significant difference (OR, 3.14 [95% CI, 0.48-20.54]; P = .23; I2 = 0%). There were no significant differences between the open repair and MIS groups in the skin necrosis and dehiscence rate, adhesion rate, or keloid scar rate. The mean surgical time was 51.0 and 29.7 minutes for open repair and MIS, respectively, with a statistically significant difference (MD, 21.13 [95% CI, 15.50-26.75]; P < .001; I2 = 15%). CONCLUSION: Open Achilles tendon repair was associated with a longer surgical time, higher risk of superficial infections, and higher risk of ankle stiffness, while MIS was associated with a greater risk of temporary sural nerve palsy. The rerupture rate and functional outcomes were mostly equivalent. We found MIS to be a safe and reliable technique. However, high-quality standardized RCTs are still needed before recommending MIS as the gold standard for managing Achilles tendon ruptures.

Risk Factors for Prolonged Opioid Use After Ankle Fracture Surgery.

BACKGROUND: The incidence of ankle fractures is increasing, and risk factors for prolonged opioid use after ankle fracture fixation are unknown. Accordingly, the purpose of this study was to investigate risk factors that lead to prolonged opioid use after surgery. METHODS: The Truven MarketScan database was used to identify patients who underwent ankle fracture surgery from January 2009 to December 2018 based on CPT codes. Patient characteristics were collected, and patients separated into 3 cohorts based on postoperative opioid use (no refills, refills within 6 months postoperative, and refills within 1 year postoperatively). The χ2 test and multivariate analysis were performed to assess the association between risk factors and prolonged use. RESULTS: In total, 34 691 patients were analyzed. Comorbidities most highly associated with prolonged opioid use include 2+ preoperative opioid prescriptions (odds ratio [OR] = 11.92; P < .001), tobacco use (OR = 2.03; P < .001), low back pain (OR = 1.81; P < .001), depression (OR = 1.48; P < .001), diabetes (OR = 1.34; P < .001), and alcohol abuse (OR = 1.32; P < .001). CONCLUSION: Opioid use after ankle fracture surgery is common and may be necessary; however, prolonged opioid use and development of dependence carries significant risk. Identifying those patients at an increased risk for prolonged opioid use can aid providers in tailoring their postoperative pain regimen. LEVELS OF EVIDENCE: Prognostic, Level III.

Non-emergent Conditions of the Ankle, Hindfoot, and Midfoot in Elderly Patients Are as Mobility Limiting as Congestive Heart Failure.

BACKGROUND: Mobility limitations are well linked to increased morbidity and mortality. Older patients with chronic pathologies of the foot and ankle can suffer from significant mobility limitations; however, the magnitude of limitation experienced by this cohort is not well characterized. Conversely, the effects of congestive heart failure (CHF) on patient mobility are routinely assessed via the New York Heart Association (NYHA) classification. New York Heart Association classification is determined by a patient's physical activity limitation and is strongly correlated to functional status. We hypothesized that non-emergent conditions of the foot and ankle would be as mobility limiting as CHF. METHODS: Life-Space Mobility Assessments (LSAs) were prospectively collected from orthopaedic patients at their preoperative visits and from CHF patients at a cardiology clinic. Patients over the age of 50 years were included in this study. Congestive heart failure patients NYHA class II or greater were included. The non-emergent foot and ankle cohort included Achilles tendonitis, ankle joint cartilage defects, ankle arthritis, subtalar arthritis, and midfoot arthritis. Patient demographics and LSA scores were analyzed using Mann-Whitney U and chi-squared tests. RESULTS: A total of 96 elderly, non-emergent foot and ankle operative patients and 45 CHF patients met inclusion criteria. All medical comorbidities, except smoking status, were significantly more prevalent in the CHF cohort. No statistical difference was observed between CHF and preoperative foot and ankle LSA scores (56.1 vs 62.4, P = .320). Life-Space Mobility Assessment scores in the foot and ankle cohort were significantly improved relative to CHF patients, at 6-month and 1-year postoperative visits (P = .028, P < .0001, respectively). CONCLUSION: Non-emergent ankle, hindfoot, and midfoot pathology is associated with similar mobility limitation to that of NYHA class II and III CHF. Older patients undergoing elective foot and ankle procedures exceeded the mobility of CHF patients at 6 months post-operation, and the mobility gains persisted at 1-year post-operation. LEVELS OF EVIDENCE: Level II: Prospective cohort study.

The Rise of Total Ankle Arthroplasty Use: A Database Analysis Describing Case Volumes and Incidence Trends in the United States Between 2009 and 2019.

BACKGROUND: Ankle arthrodesis has been the mainstay treatment for end-stage ankle arthritis. The popularity of total ankle arthroplasty (TAA) has been on the rise due to improved implant design and postoperative outcomes. The purpose of this study was to describe the basic epidemiology and trends of annual procedure volumes and incidence in the general American population as well as in different population subgroups from 2009 to 2019. We hypothesize that the incidence of TAA has significantly risen while the median length of hospital stay has decreased nationwide. METHODS: The IBM MarketScan database was queried for patients who underwent TAA from January 2009 to December 2019 based on Current Procedural Terminology coding. Population estimates from the US Census Bureau were used to calculate the annual incidence of TAA. Procedural volume and incidence were calculated for annual sums, gender, age subgroups, inpatient and outpatient TAA, as well as in four statistical geographic regions in the United States. Median length of hospital stay was calculated and trended annually for inpatient TAA. RESULTS: A total of 41,060 primary TAAs were identified in the database from 2009 to 2019, in which 52.5% were performed in males. Annual volumes increased by 136.1%, from 2180 to 5147 procedures nationwide. Incidence reported per 100 000 population increased by 120.8%. Both inpatient and outpatient procedures have increased, by 242.5% and 86.6%, respectively. Median length of hospital stay decreased from 3 days in 2009 to 1 day in 2019 and did not differ between genders. Growth in incidence was demonstrated in males and females above the age of 54 years with the largest growth in annual incidence found between 65 and 74 years. Incidence rose in the South and West of the United States by 111.8% and 136.5%, respectively. CONCLUSION: We found that annual volumes and incidence rates of primary TAA has increased between 2009 and 2019. Although both inpatient and outpatient surgery have become more frequent, inpatient volumes and incidence have increased almost 3 times more than those of outpatient surgery. Length of hospital stay decreased over the study years. When adjusted for the same study period, the cumulative annual growth rates of TAA were found to be 2 times greater than total knee arthroplasty and 3.6 times greater than total hip arthroplasty.

Effect of Obesity on Patient-Perceived Outcomes After First Metatarsophalangeal Joint Arthrodesis.

BACKGROUND: While first metatarsophalangeal joint (MTPJ) arthrodesis is a common and effective procedure, there is a paucity of studies examining obesity's effect on outcomes of 1st MTPJ arthrodesis. This study's purpose was to evaluate patient-reported outcomes following 1st MTPJ arthrodesis in obese versus non-obese patients. METHODS: A retrospective cohort study of 94 patients undergoing first MTPJ fusion over the age of 18 with a diagnosis of hallux valgus or hallux rigidus was performed. Surgical and postoperative outcomes were examined preoperatively and at 6 and 12 months follow-up via Visual Analog Pain scale (VAS), and Short Form 36 (SF-36) surveys, and data were stratified into 2 patient groups: BMI < 30 (n = 62, mean age 63.9 ± 9.1 and ≥ 30 (n = 32, mean age 61.9 ± 8.4). RESULTS: Average overall VAS and SF-36 physical component scores improved significantly at 6 months (P < .001, .006) and 1 year postoperative visits (P < .001, .007) with no differences in survey scores, outcomes, or complications between weight groups. CONCLUSION: Our study showed first MTPJ fusion improves short-term pain and physical quality-of-life in arthritic obese and non-obese patients without differences in nonunion, complications, or patient-reported measures. LEVEL OF EVIDENCE: Level III, Prognostic, Case-Control Study.

Complications of Lesser Toe Surgery: How To Avoid Them before Surgery and How To Assess and Treat Them When They Have Occurred.

Complications following lesser toe surgery are challenging to manage. The keys to treatment of any of these conditions are, first, to try to avoid them through identification of patient- and surgeon-related variables that contribute to their development and, second, following the occurance of a complication, to understand what can and cannot be corrected with surgical and nonsurgical management. This review provides a comprehensive assessment of current literature, demonstrates best practices and approaches to lesser toe complications, and provides an illustration of clinical examples.

Preoperative Depression is Associated With Increased Complications Following Ankle Fracture Surgery.

BACKGROUND: The effects of preoperative depression following ankle fracture surgery remains unknown. The purpose of this study is to investigate the relationship between preoperative depression and outcomes following ankle fracture surgery. METHODS: This retrospective study used the Truven MarketScan database to identify patients who underwent ankle fracture surgery from January 2009 to December 2018. Patients with and without a diagnosis of preoperative depression were identified based on International Classification of Diseases (ICD) codes. Chi-squared and multivariate analyses were performed to determine the association between preoperative depression and postoperative complications following ankle fracture surgery. RESULTS: In total, 107,897 patients were identified for analysis, 13,981 of whom were diagnosed with depression (13%). Preoperative depression was associated with the increased odds for postoperative infection (odds ratio [OR]: 1.33, confidence interval [CI]: 1.20-1.46), wound complications (OR: 1.13, CI: 1.00-1.28), pain-related postoperative emergency department visits (OR: 1.58, CI: 1.30-19.1), 30-day and 90-day readmissions (OR: 1.08, CI: 1.03-1.21 and OR: 1.13, CI: 1.07-1.18), sepsis (OR: 1.39, CI: 1.12-1.72), and postoperative development of complex regional pain syndrome (OR: 1.46, CI: 1.18-1.81). CONCLUSION: Preoperative depression is associated with increased complications following ankle fracture surgery. Further studies are warranted to investigate the degree to which depression is a modifiable risk factor. LEVEL OF EVIDENCE: 3.

Donor site morbidity of calcaneal, distal tibial, and proximal tibial cancellous bone autografts in foot and ankle surgery. A systematic review and meta-analysis of 2296 bone grafts.

PURPOSE: This study aims to report on the safety and donor site morbidity of the distal lower extremity (calcaneal, proximal, and distal tibial) cancellous bone autografts. We summarized the findings in a comprehensive infographic illustration. We are unaware of any similar meta-analyses to date. METHODS: Following the PRISMA guidelines, two independent investigators searched MEDLINE (PubMed), EMBASE, SCOPUS, Google Scholar, and Cochrane databases in December 2020 using the following keywords and their synonyms: ("bone graft", "donor site morbidity", "calcaneal graft", "proximal tibia graft", and "distal tibia graft"). Besides, the reference lists from previous review articles were searched manually for eligible studies. The primary outcomes of interest were (1) chronic pain, (2) fracture, and (3) infection, whereas the secondary outcomes were (1) neurological complications, (2) sensory disturbance and hypertrophic scars, (3) other complications such as shoe-wear difficulties and gait disturbance. Inclusion criteria were: studies on complications and adverse events of lower extremity bone autografts (calcaneal, proximal tibial, and distal tibial bone autografts) reporting at least one of the desired outcomes. Studies not reporting any of the outcomes of interest or if the full text is not available in English were excluded. Studies reporting on bone marrow aspirate or autografts for non-orthopedic indications were also excluded. RESULTS: After the removal of duplicates, a total of 5981 studies were identified. After screening those records, 85 studies remained for full-text assessment. Out of those, 15 studies qualified for the meta-analysis with a total of 2296 bone grafts. Out of those grafts, 1557(67.8%) were calcaneal grafts, 625 (27.2%) were proximal tibial grafts, and 114 (5%) were distal tibial grafts. In calcaneal bone grafts, there were 28 cases of chronic pain [1.97%, CI:1.10-2.50%, I2 = 66%], 5 fractures [0.32%, CI: 0.10-0.60%,I2 = 0%], 20 sural neuritis [1.28%, CI:0.70-1.80%, I2 = 0%), and no wound infections. In proximal tibial grafts there were 13 cases of chronic pain [2.08%, CI: 1.01-3.2%, I2 = 34.5%], 1 fracture [0.16%, CI:0.10-0.50%, I2 = 0%], and 3 superficial wound infections [0.48%, CI: 0.10-1.01, I2 = 0%]. In the distal tibial grafts there were no cases of chronic pain or wound infections, 1 fracture [0.90%, CI: 0.80-2.6%, I2 = 0%], and 5 saphenous neuritis [4.5%, CI: 0.70-8.40%, I2 = 65%]. CONCLUSION: Calcaneal, distal tibial, and proximal tibial bone autografts are safe with a low rate of overall and major complications. We report an overall complication rate of 6.8%, which is less than half of that previously reported for iliac crest grafts. The authors recommend using distal lower extremity grafts for foot and ankle primary surgeries instead of iliac crest grafts when indicated. Clinical trials with a large sample size are required.

Preoperative Depression Influences Outcomes Following Total Ankle Arthroplasty.

INTRODUCTION: Total ankle arthroplasty (TAA) is increasing in incidence. While preoperative depression is known to affect outcomes following other procedures, its effect on outcomes following TAA are unknown. Therefore, the purpose of this study was to investigate this relationship. METHODS: This is a retrospective cohort study using the Nationwide Readmission Database (NRD). All patients undergoing TAA were included. Two cohorts (those with and without preoperative depression) were created. Logistic regression was then performed to assess the contribution of a preoperative diagnosis of depression on rates of 90-day complications, while controlling for patient demographic and comorbid data. RESULTS: Overall, 8047 patients were included, of whom, 11.4% (918) were depressed. Compared to patients without depression, patients with depression had increased odds of the following: nonhome discharge (OR 1.61, 95% CI 1.31-1.98), extended length of stay (>2 days; OR 1.34, 95% CI 1.15-1.57), prosthetic complication (OR 1.39, 95% CI 1.10-1.74), wound complication (OR 1.59, 95% CI 1.11-2.29), prosthetic joint infection (OR 1.82, 95% CI 1.06-3.15), superficial surgical site infection (OR 1.62, 95% CI 1.02-2.58), and medical complication (OR 1.32, 95% CI 1.03-1.68). DISCUSSION: Depression in patients undergoing TAA is common and is associated with increased health care utilization and complications following surgery. The modifiability of depression should be investigated with future studies. LEVELS OF EVIDENCE: Prognostic, Level III: Comparative study.

Return to sport following navicular stress fracture: a systematic review and meta-analysis of three hundred and fifteen fractures.

PURPOSE: This meta-analysis aims to provide updated evidence on the success rate, return to play (RTP) rate, time to RTP, and complications of operatively and conservatively managed navicular stress fractures (NSFs) as well as delays in diagnosis while avoiding limitations of previous similar studies. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, two independent team members electronically searched MEDLINE (PubMed), EMBASE, Google Scholar, SCOPUS, and Cochrane databases throughout February 2021 using the following keywords with their synonyms: "Navicular stress fracture," "return to play," and "athletes." The primary outcomes were (1) management success rate, (2) RTP rate, and (3) time to RTP. The secondary outcomes were (1) non-union, (2) time to diagnosis, (3) refracture, and (4) other complications. Inclusion criteria were clinical studies on NSFs reporting at least one of the desirable outcomes. Studies not reporting any of the outcomes of interest or the full text was not available in English, German, French, or Arabic were excluded. Case reports, case series with less than ten cases, and studies reporting exclusively on navicular non-union management were also excluded. The Newcastle-Ottawa scale was used for quality assessment while Review Manager (RevMan) Version 5.4 was used for the risk of bias assessment. Data were presented by type of treatment (surgical or conservative). If enough studies were present that were clinically and statistically homogeneous and data on them adequately reported, a meta-analysis was performed using a fixed-effects model. In case of statistical heterogeneity, a random-effects model was used. If meta-analysis was not possible, results were reported in a descriptive fashion. The need to explore for statistical heterogeneity was determined by an I2 greater than 40%. RESULTS: Eleven studies met the inclusion criteria with a total of 315 NSF. Out of those, 307 (97.46%) NSFs were in athletes. One hundred eight (34.29%) NSFs were managed operatively, while 207 (65.71%) NSFs were managed conservatively. Successful outcomes were reported in 104/108 (96.30%) NSF treated operatively with a mean success rate of 97.9% (CI: 95.4-100%, I2 = 0%). Successful outcomes were reported in 149/207 (71.98%) NSF treated conservatively, with a mean success rate of 78.1% (CI: 66.6-89.6%, I2 = 84.93%). Successful outcome differences were found to be significant in favor of operative management (OR = 5.52, CI: 1.74-17.48, p = 0.004, I2 = 4.6%). RTP was noted in 97/98 (98.98%) NSF treated operatively and in 152/207 (73.43%) NSF treated conservatively, with no significant difference between operative and conservative management (OR = 2.789, CI: 0.80-9.67, p = 0.142, I2 = 0%). The pooled mean time to RTP in NSF treated operatively was 4.17 months (CI: 3.06-5.28, I2 = 92.88%), while NSF treated conservatively returned to play at 4.67 months (CI: 0.97-8.37, I2 = 99.46%) postoperatively, with no significant difference between operative and conservative management (SMD = - 0.397, CI: - 1.869-1.075, p = 0.60, I2 = 92.24). The pooled mean duration of symptoms before diagnosis was 9.862 (3.3-123.6) months (CI: 6.45-13.28, I2 = 94.92%), reported in ten studies. Twenty (23.53%) refractures were reported after conservative management of 85 NSFs, while one (1.28%) refracture was reported after operative management of 78 NSFs, with a significant difference in favor of operative management (OR = 0.083, CI: 0.007-0.973, p = 0.047, I2 = 38.78%). CONCLUSION: Operative management of NSF provides a higher success rate, a lower refracture rate, and a lower non-union rate as compared to other non-operative management options. While not significant, there is a notable trend towards superior RTP rates and time to RTP following operative management. Therefore, we recommend operative fixation for all NSFs type I through III in athletes. Athletes continue to exhibit an alarmingly long duration of symptoms before diagnosis is made; a high index of suspicion must be maintained, therefore, and adjunct CT imaging is strongly recommended in the case of any work-up. Unfortunately, the published literature on NSFs remains of lower level of evidence and high-quality studies are needed.

Complications Associated with the Surgical Management of Hallux Rigidus.

Hallux rigidus is the most common arthritic pathology of the foot. This review article discusses the pathophysiology and common clinical presentation of hallux rigidus. Furthermore, we discuss multiple classification systems that categorize the arthritic process and guide management. Surgical interventions include cheilectomy, Moberg osteotomy, synthetic cartilage implants, interpositional arthroplasty, and arthrodesis. The common complications are reviewed, and the rates of these complications highlighted. Surgical options for hallux rigidus globally have successful outcomes with low rates of complications when done on appropriate patients.

Telemedicine Foot and Ankle Visits in the COVID-19 Era.

BACKGROUND: The COVID-19 pandemic created a difficult environment to provide musculoskeletal care to patients with foot and ankle pathology given the limitations placed on in-office visits. Telemedicine offered a unique avenue to reach these patients; however, the efficacy of telemedicine visits in patients with foot and ankle pathology is not well studied. We propose a telemedicine protocol that has allowed us to effectively see and treat patients with foot and ankle pathology. METHODS: A 12-step standardized telemedicine protocol was created within the Foot and Ankle division that was used for seeing patients through telemedicine. Also included in this is previsit preparation and follow-up recommendations. Press Ganey surveys were retrospectively reviewed to understand patient experience with telemedicine. RESULTS: 85.2% of patients surveyed responded with scores indicating excellent care. When comparing patients who were seen in-office and through telemedicine, 89.2% and 83.4% responded with scores indicating excellent care, respectively (P = .37). CONCLUSION: Telemedicine offers an effective and convenient way to provide excellent musculoskeletal care to patients affected with foot and ankle pathology. This is the first study that evaluated a comprehensive protocol for telemedicine encounters and can be used to implement telemedicine by others using this approach.
